Abstract

Invasive plants such as Pueraria montana, or kudzu, are a growing problem in many parts of the world. Research was conducted to understand how these plants spread so quickly, and if allelopathy was one of the factors that caused its spread. The purpose of this experiment was to find how P. montana leachate affects the germination of Chamaecrista fasciculata. It was hypothesized that the leachate would inhibit the germination of C. fasciculata the most at 30 g/L concentration of leachate. Different concentrations of the leachate were made at 0 g/L, 10 g/L, 20 g/L, and 30 g/L. For each concentration, 24 seeds were tested using 5 ml of leachate for every 3 seeds. The seeds were incubated at 25°C for 7 days, and radicle lengths were measured. A one-way ANOVA test was conducted to compare the effect of the concentration of P. montana leachate on germination length. There was no significant difference between the different concentrations, F(3,92) = 0.41, p = 0.744. This means that P. montana leachate had no effect on C. fasciculata and might not use allelopathy against this plant.
